When Panthers defensive end Greg Hardy pounced on his one-year, $13.1 million franchise tender, he left open the possibility of staying away from voluntary offseason workouts for leverage in talks toward a long-term deal. He won’t be staying away, and the Panthers have given him $1.3 million reasons to show up. Per a league source, the Panthers and Hardy have agreed to formula pursuant to which Hardy can earn an advance of $1.3 million by showing up for the full offseason program. Hardy will get paid by the week throughout the offseason program. Absent such an arrangement, Hardy wouldn’t have gotten any of his $13.1 million until September. So he can make roughly 10 percent of his 2014 salary now, simply by doing that which he already had an incentive to do — prepare to have a monster season in advance of hitting the market. (Unless, of course, the Panthers choose to tag him again in 2015, at $15.72 million.) For a guy who completed a slotted sixth-round contract, $1.3 million matches the most he has made in any of his four NFL seasons.
